Temperature- and Pressure-Dependent Structural Studies of ɣ-PtBi₂

Abstract

Trigonal PtBi₂ is a promising platform for several phenomena that are rarely observed together. It exhibits topological properties, surface superconductivity, and has also been proposed as a potential host for Majorana fermions, quasiparticles of considerable interest for quantum computing. Although some of its properties have been studied, important aspects remain to be clarified. In the present work, we perform pressure-dependent x-ray diffraction (XRD) measurements to investigate the crystal structure under varying pressure conditions. In addition, we analyze the electronic structure using ab initio density functional theory (DFT) calculations.
